Battery_Bank_Upcycled_18650

As a bicycle mechanic I recovered a couple of e-bike batteries.

As an electronic user I had a portable battery in which packs inflated.

As a guy who doesn't like to put to the bin too easily I merged the two with some R-PETG and TPU (not recycled) and wires from e-bike battery. As often with my model dimensions are what they are, free to you to edit the FREECAD file to fit your need (different elec, need to make the micro usb available, whatever)

The electronic is marked: PW37-05 UL94 V0

The cell spring and plot can be found here: https://www.amazon.fr/Batterie-Positif-Conversion-Nickelage-Tokaneit/dp/B0BJ6HP86G/ref=sr_1_1?__mk_fr_FR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=20CO2MMTD0FOW&dib=eyJ2IjoiMSJ9.ioFhEsQcmEku30wVlwNKJw.dNK7qZ8IZNSs2OLC0cW8Z2S8e87FsPbGm8ucKxbmv5k&dib_tag=se&keywords=tokaneit%2Bpositive%2Bnegative&qid=1713698363&sprefix=tokaneit%2Bpositive%2Bnegative%2Caps%2C52&sr=8-1&th=1

For the positive side you will need to cut or adjust the top part of the holder to fit the terminal as the central well is for negative and not accessible.

I advice you to solder each terminal with its wire before passing it through.

I split the holder in two to avoid too much support.

The 3mf contains last stl uploaded. And is for a Prusa mini with input shaper and mini sherpa direct drive. Last filament used is a TPU.

For the seal, as you can see by comparing picture and stl I comdemned the micro_usb ports. 1 I won't use it (works only to charge the bank and needed to reprint the petg top to fit the plastic part around normal micro-usb).

The elastic band are here to secure the assembly in my backpack. More elegant solution can be found. Redesign of bottom and top interface for example.
